Excel/Due Dates

QuestionI work in construction. We'd like to know if there is a way to work a calendar backwards. We have a "due on site" date, a material lead time and need to figure out when the item needs to be approved by in order to meet the "due on site" date.

Please help, thank you for your time.

AnswerHi Katy
How are you?

You can substract and add days to any date as if it were simple numbers:

Eg.
Type
the due date in C1
the number of days that takes to receive the part in B1
the orderīs date should be in A1
=C1-B1

if the result comes on a numeric format, just change it to a date format.
